How to Build

This is a procedure to easily build by delegating the build of dependent packages to vcpkg. The procedure is as follows.

Setup vcpkg

This allows you to set up alembic and pybind11, which mmdbridge's build depends on.

• Clone vcpkg.
• Execute bootstrap-vcpkg.bat to build vcpkg.

Install dependent libraries with vcpkg

Note that chcp 65001 is required.

chcp 65001
vcpkg install alembic[hdf5]:x64-windows pybind11:x64-windows

Build artifacts are stored under VCPKG_DIR/installed/x64-windows, which will be used in subsequent steps. Please set the environment variable VCPKG_DIR to the top-level directory of vcpkg.

Example:

VCPKG_DIR=C:/vcpkg

Preparing DirectX SDK

Since old D3D9 is required, you need to install the SDK.

• https://www.microsoft.com/en-us/download/details.aspx?id=6812

Please set the installation path to the environment variable DXSDK_DIR.

Example:

DXSDK_DIR=C:/Program Files (x86)/Microsoft DirectX SDK (June 2010)

Pre-build modification work

Before building mmdbridge, you need to modify the following files.

Modifying d3dx9core.h

Please modify according to https://gist.github.com/t-mat/1540248#d3dx9corehを参考に修正してください.

Change

#ifdef UNICODE
    HRESULT GetDesc(D3DXFONT_DESCW *pDesc) { return GetDescW(pDesc); }
    HRESULT PreloadText(LPCWSTR pString, INT Count) { return PreloadTextW(pString, Count); }
#else
    HRESULT GetDesc(D3DXFONT_DESCA *pDesc) { return GetDescA(pDesc); }
    HRESULT PreloadText(LPCSTR pString, INT Count) { return PreloadTextA(pString, Count); }
#endif

to

#ifdef UNICODE
    HRESULT GetDesc(D3DXFONT_DESCW *pDesc) { return GetDescW(reinterpret_cast<ID3DXFont*>(this), pDesc); }
    HRESULT PreloadText(LPCWSTR pString, INT Count) { return PreloadTextW(reinterpret_cast<ID3DXFont*>(this), pString, Count); }
#else
    HRESULT GetDesc(D3DXFONT_DESCA *pDesc) { return GetDescA(reinterpret_cast<ID3DXFont*>(this), pDesc); }
    HRESULT PreloadText(LPCSTR pString, INT Count) { return PreloadTextA(reinterpret_cast<ID3DXFont*>(this), pString, Count); }
#endif

Preparing the MikuMikuDance_v932x64 folder

Extract the 64-bit version of MMD into the MikuMikuDance_v932x64 folder.

mmdbridge
    MikuMikuDance_v932x64
        MikuMikuDance.exe

Building mmdbridge

Execute cmake_vs2022_64.bat and build the generated build_vs2022_64/mmdbridge.sln. Building INSTALL will copy the necessary dll and py files for execution to MikuMikuDance_v932x64.

Debug execution of mmdbridge

You can attach the debugger by specifying MikuMikuDance_v932x64/MikuMikuDance.exe in INSTALL project properties - Debug - Command - Browse and running with F5. In debug builds, pdb is embedded with the /Z7 compile option.
